My older brother has always been prone to colds and had a weak constitution. When I was little, I gave him a kiss coupon as a birthday present—my way of wishing him well and hoping a kiss would make him better. As the years passed and we both grew up, that kiss coupon remained a cherished memory between us, even into our school days. One day, my brother suddenly hands me back the kiss coupon. In that single moment, buried feelings begin to surface, setting in motion a poignant story that changes our relationship forever.
